I have installed the latest version of USB loader gx. I have NTFS Wii ver 4.3 hacked using ModMii with latest hacks. All games I've found and installed work, though I can't get the USB controllers to work in Rock Band 1 or the Beatles Rock Band from usb loader. I tried applying a cIOS 222 and running it under the game settings (described here) but this method may be out of date at this point. As far as that method goes, I tried the hack I have installed already, then uninstalled ios 222 and reinstalled it like mentioned in the link. Like I said, I've applied most of the hacks already, but there is clearly something that I am missing in order to make the USB instruments work. I have USB Loader mounted to port 0, so I have to put the instruments in the other port. Any up to date advice about this would help. Thanks.
